Question for FM 'DYNP_VALUES_READ'

Former Member · ‎04-23-2009

Hi

I have a question for FM 'DYNP_VALUES_READ'.

I'd like to use this FM for check input values of several PGM in runtime.

When I tested this FM, An error code returned instead of field values.(INVALID_DYNPRONAME)

The FM was called in Start-Of-Selection of PGM with runtime PGM names , screen fields, dynpread table.

To solve this problem I reviewed sample PGMs, and I noticed that this FM used only for F4 help value request and field chain in subscreen.

How can I solve the problem?

Pleas help me.

HI,

This need to be used when you call the F4 help on particular field.

Exmaple...the requirement is to show F4 help on the particular filed B depending on the value entered in Field A..in this case you will not get the value of field A in the event AT SELECTION-SCREEN ON VALUE-REQUEST/POV . O get the get value of field A you need to use the DYNP_VALUES_READ.

Hello everyone

The "DYNP_VALUES_READ" doesn't work when we are at the "START-OF-SELECTION" section.

Is there any function that will work like "DYNP_VALUES_READ" but from the "START-OF-SELECTION" section?

I need it to be able to use the screen value in a method from a customized class.

The following code doesn't work. We always obtaining the error invalid_dynproname because the call function "DYNP_VALUES_READ" is inside the "START-OF-SELECTION" section.

I need a function that is working inside the "START-OF-SELECTION" section.

REPORT ztest20.

DATA: lt_dynfields TYPE TABLE OF dynpread,
      ls_dynfields LIKE LINE OF lt_dynfields.

PARAMETERS: p_lcf AS CHECKBOX DEFAULT.

START-OF-SELECTION.

  REFRESH lt_dynfields.
  ls_dynfields-fieldname = 'P_LCF'.
  APPEND ls_dynfields TO lt_dynfields.

  CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname               = 'ZTEST20'
      dynumb               = '1000'
    TABLES
      dynpfields           = lt_dynfields
    EXCEPTIONS
      invalid_abapworkarea = 1
      invalid_dynprofield  = 2
      invalid_dynproname   = 3
      invalid_dynpronummer = 4
      invalid_request      = 5
      no_fielddescription  = 6
      invalid_parameter    = 7
      undefind_error       = 8
      double_conversion    = 9
      stepl_not_found      = 10
      OTHERS               = 11.
  IF sy-subrc <> 0.
  ENDIF.

  WRITE:/ sy-subrc.
